• ## The Mechanics of Electro-Magnetic Radiation.

Posted on April 14th, 2016

The mechanics of any thing means how it actually works. Primarily, electromagnetic radiation means movement of electrons by means of a magnetic force. Radio waves can be created by electromagnetic radiation but generally are not. A dynamo creates electricity by using a magnetic field that accelerates electrons. A battery does not produce electricity by magnetics but by chemical reaction. Therefore light from a torch is not electro-magnetic radiation.

The magnetic field generated to move iron filings in school experiments is similar to electro-magnetic radiation in that it moves particles, in this case, iron filings. A single magnetic pulse will move iron filings. a second pulse may move them a little further. further pulses may or may not cause any extra movement.

When a force is momentarily applied to an object and the force is sufficient to move the object, then one of two things will happen. If there is no resisting force acting apart from inertia, then the object will continue moving after the force is removed. In other cases the object will slow down and then stop.

With a magnetic field pulse each step forward reduces the force available to move the object during the next pulse. A magnetic field is not a constant force, the force exerted depends on the distance from the object.

Magnetic fields have a very limited range relative to the force that they can produce. This means that a reversing force field acting on a small mass will lose effective contact with it. The outward force may accelerate the object to a distance beyond reach of the following inward force.

A further point to consider is the ‘velocity’ of the force field. If you consider a paper bag being blown along by the wind, the wind will be travelling faster than the paper bag, (if it wasn’t there would be no force acting on the paper bag and it would fall.). It is assumed that a force field propagates instantaneously. but I am not yet convinced of this, but am unable to put forward a reasonable argument against it. What is certain is that the rate of propagation is faster than 300,000 kilometres per second.

Relating to electrons this means that a magnetic pulse will pass through a cloud of electrons, irrespective of their velocity. This brings in a further complication to an already complex problem.

There is no such thing as ‘instant acceleration’. It takes time to increase a velocity. Even an electron has inertia, plus an electron is subject to resistance from whatever substance that is travelling through.
